Hi John,

you can use a hook for that, before task partition is called. First use 
fai-mount-disk -f
for mounting the local disk according to the fstab. Then check if
there are files in $target/home. If files are found, stop the
installation, otherwise call fai-mount-disk -u to umount the local
file systems and go on with the installation.
